FIELD OF THE INVENTION

This invention relates to travel sleeping aids for assisting a seated traveler to sleep in a forward leaning seated position toward a passenger seat in front of the seated traveler.

BACKGROUND OF THE INVENTION

Seated travelers in a wide range of transportation systems including inter alia airplanes, trains, buses, and the like, tend to fall asleep during long journeys. The seating arrangements in most transportation systems do not allow a full horizontal position and therefore the seated passenger has to sleep in a seated position. Many seated travelers complain of bad sleeping posture while sitting and neck pains due to lack of support for their heads.

Travel sleeping aids can be generally classified into two categories: First so-called body worn travel sleeping aids in the form of inflatable travel pillows, non-inflatable travel pillows, head or neck restraining arrangements, and the like. And second, so-called body support travel sleeping aids intended to be supported or suspended from a travel sleeping aid support.
